As far as Whipple, per Ford Rep the intercooler, CAI, any exhaust and tune together, independently or a combination there of DO NOT VOID any part of the 5/60 warranty. Whipple is who Shelby, Rousch and SCA Performance use with no issues on the warranty. Ford accepts their products and was consulted with by Whipple when designing the CAC (Intercooler) and the CAI. Anyone who says different is lying and trying to sell you what they have or their margins are greater if they unload what they stock.
Not sure what “Ford rep” you spoke with, but that is incorrect. If any modification can be attributed to a failure, it is not warrantable. So if your engine melts down a piston and you’re tuned, you’re paying the repair bill, not Ford warranty.
Whipple, Shelby, Roush (not Rousch), and SCA modifications/packages are NOT covered under factory warranty if their modifications can be attributed or associated with the failure. Ford does not control nor accept any responsibility for the products that those companies produce; the vehicle is simply shipped to the modifier/upffiter after leaving the manufacturing plant. This is why many of those companies include a separate warranty when you purchase their products. However, their warranties are typically only 3/36, and do not match the factory 5/60 powertrain. So if you’re out of their 3/36 and you blow an engine in your tuned Shelby Raptor, you as the consumer is responsible for the repair costs.
All of this information is straight from Ford Motor Company’s Warranty & Policy Manual, as well as Ford’s dealer communications. In fact, they just published the following Service Message in January:
SSM 48491
2018-2020 F-150 vehicles equipped with an aftermarket supercharger kit do not carry coverage for the aftermarket components under the Ford New Vehicle Limited Warranty. These aftermarket components include, but are not limited to, supercharger, A/C compressor pulley, belt tensioner, and belt. The Roush Performance supercharger kit may carry a 3-year/36,000 mile limited powertrain warranty through Roush Performance. For assistance with Roush warranty pre-authorization and payment contact Roush Performance. Ford Performance Parts kits may carry a 3-year/36 ,000 mile warranty through Ford. Dealers should contact the Ford Performance Parts call center (800-367-3788) for warranty pre-authorization, payment, and diagnostic support for parts purchased through a Ford Performance Parts dealer.
Secondly per the Magnuson Moss Warranty Act of 1975, it is illegal for a dealer or manufacturer to deny any claims or any work under warranty by claiming any and all aftermarket parts caused the damage, excessive enough to damage the vehicle, motor, powertrain, electronics, etc. Which is to say they can tell you that buy not keeping oil in the car, blowing up the motor is your fault but they can't say because you used Mobil 1 oil and filter as opposed to Motorcraft you have voided your manufacturers warranty.
MM only applies to OE equivalent parts. So, as you state, the dealer or OEM cannot void your warranty simply because you used Mobil 1 instead of Motorcraft engine oil. However, if the “OE equivalent” part caused the failure, such as the Fram oil filters that disintegrate and destroyed Modular 3V engines, that is not warrantable. MM has nothing to do with aftermarket modifications/performance upgrades; once you change a powertrain calibration, you are responsible for any damage that can be attributed to that modification.
Neither Ford or any dealer in the country can prove that your motor blew up because of your intake. Now if they investigate and find the intake clogged with paper, leaves, dirt, twigs, etc and you still attempted to drive the vehicle then yes you are screwed but not by the equipment on the vehicle but rather operator negligence.
That depends. On MAF equipped vehicles, aftermarket intakes can skew MAF readings, which consequently skew fuel trims and negativity affect engine performance. If an engine ran lean and burned the valves and the aftermarket intake was found to be skewing the fuel trims, that is a non-warrantable failure. On a speed density system like the EcoBoost, that is a non-issue, but it’s still possible to have a poor connection or poor filtration that allows the engine to Ingest dirt, which is of course is a non-warrantable failure.
